"I haven't been told that and the family hasn't been told that," he said.

The travel company that booked the schoolies' trip to Fiji described the death as a "tragic accident".

"The parents of the teenager involved in the tragic accident at Plantation Island Resort have been notified and all other guests are safe and well, being well cared for during this unfortunate time," Unleashed Travel said on its Facebook.

Fiji police could not confirm reports the teenager had been playing a hold-your-breath dare game before he died.

‘‘All I know is that he went into the pool and didn’t come out,’’ the spokesman said.

The police spokesman said there were about 500 schoolies staying on the island, and they were holding nightly parties between 7pm and 5am.

News Limited reports the teen may have been taking part in a "breath dare'' game - where participants compete to hold their breath underwater - when tragedy struck.

In a statement, a DFAT spokesperson said: ‘‘We can confirm the death of a 17-year-old male from Queensland in Fiji overnight.’’

According to a recent college newsletter, Harrison contributed to the creation of a new sporting motto "TEAM MORE – Together, Everyone, Achieves, More”.

"This motto you will see around the college for many years to come," the newsletter read.

It’s the second schoolies death during this year’s celebrations after Brisbane school leaver Isabelle Colman, 17, fell to her death from the 26th floor of the Chevron Renaissance apartment tower at Surfers Paradise late last month.

‘‘From a school perspective, the community is shocked,’’ Brisbane Catholic Education spokesman John Phelan said of the latest tragedy.
